Substitute complicated with disputed and I agree lol. The Irish Government strongly dispute the term British Isles being applied against our wishes to this island, as it was invented to legitimise a land claim, not innocently by any neutral geographic body.
Unlike Scotland we've a treaty which now sets out our democratic pathway to getting the British government to finish their withdraw from our island, but we're no closer to holding the vote (and don't control the trigger).
Still raw Scotland missed their chance, but that too is a complicated topic!
No worries, I'm not trying to trick you, you of course are right, it's complicated.
Back to the original topic, what really gets me is shows like Rings of Power double down on Tolkien classism by accent - intelligent elegant Elf's in posh English, common men in northern English, rough ginger dwarfs in Scottish and then bottom of the class - mud dwelling, starving savage hobbits with Irish accents
